On Monday, the couple was reportedly arguing on Interstate 90 heading west near Avon, Ohio, when another motorist stopped to see what they were arguing about, according to Crowley's statement. The other motorist called Avon police, who questioned Manziel and Crowley about the incident. According to Northeast Ohio Media Group, the police report states Crowley told officers Manziel hit her and pushed her head into the window.

However, Crowley only showed a wrist abrasion and no other signs of bodily harm, according to the report. Manziel also admitted to having two drinks earlier in the day, and Crowley was “impaired.”

Crowley opted not to press charges, and neither she nor Manziel were arrested for the incident. Police let them both go.

The fact that the incident involved alcohol does create complications for Manziel. He spent 10 weeks this past off-season period in an addiction treatment center, putting his NFL career on hold. The Browns supported Manziel's decision, and the team since brought him slowly back into the fold.

Browns general manager Ray Farmer issued a statement after the issue became public, but he sidestepped revealing any more details.

"We were aware of the situation,'' Farmer said. "It is a matter that we take seriously and have expressed our concerns to Johnny directly. Those conversations will remain private, and we will refrain from further comment at this time.''

Manziel is still expected to act as backup to starter Josh McCown in Sunday's matchup with the visiting Denver Broncos.
